A student received a 75% on an exam. If there were 20 questions on the exam, which ratio would show the number of questions answered correctly?A. 15:20
B. 20:15
C. 5:20
D. 20:5

Answers

Answer 1
Answer: Assuming the question is asking for the ratio of questions answered correctly to the number of questions, A is the correct answer. 75% of 20 is 15 ((20/4) x 3), so 15:20 is correct, though this can be cancelled to 3:4. If the question asks for the ratio of correct to incorrect answers, the ratio would be 15:5, or 3:1.

Suppose the circumference of a circle is 8π. What is its area?

Answers

Circumference = (π) x (diameter)
Circumference = 8π
(π) x (diameter) = 8π
Diameter = 8
Radius = 4

Area = π x (Radius)²
Area = π x (4)²
Area = π x (16) = 50.27 units² (rounded)
Well, its diameter would be 8, making its radius 4. The formula for finding the area of a circle is π x radius^2. So, the area would be ^2.
